Abstract
The invention relates to a surface treatment process for an aluminum base material conductor bus way. The surface treatment process includes the steps of primary workpiece surface treatment, molecular osmotic treatment, plating and secondary workpiece surface treatment. By means of the surface treatment process for the aluminum base material conductor bus way, the surface oxidation resistance of an aluminum material is achieved, the surface conductivity is improved, and the contact resistance is lowered. The novel aluminum alloy bus way serves as a conductor, and on the premise of guaranteeing safe power supply, the cost of the bus way is greatly reduced. Compared with a copper conductor bus way with the same current-carrying capacity, the cost of the aluminum material bus way is only 30-35% that of the copper conductor product, so that the aluminum base material conductor bus way is economical.
